main/postmarketos-ui-*: replace auto start scripts with lightdm for X11 DE's
This replaces !39 (closed).
All X11 DE's now autologin using LightDM.
I tried making it work for Weston and Plasma Mobile, but they're having some issues with it right now so I decided to just go with the X11 DE's first. They all work for me, but I like someone to try it out on an actual device.
